Suspected vandals broke into a parked B train in the Bronx on Sunday night, one of several subway vandalism incidents reported on the eve of Monday’s blizzard.
Sources tell the Daily News the unidentified trespassers broke into the train while it was parked on the express track at the 174th-175th St. station in Tremont and moved it a few car lengths.
Somehow, sources said, the vandals also damaged a master door controller — the control panel that allows a train operator or conductor to open and close the train’s doors.
The trespassers, described as “kids” by sources, were seen on the train by a transit worker, but fled before they could be confronted.
An MTA spokesman did not immediately respond to questions about the train’s condition and whether it was still in service.
Sources told The News the break-in was one of several apparent vandalism incidents in the subway system between Sunday night and Monday morning.
Graffiti was reportedly found overnight on parked subway trains at the underground 174th St. Yard in Washington Heights serving the C train, as well as at the 240th St. Yard of the No. 1 train near Van Cortlandt Park in the Bronx.
Sources also told The News a number of trains parked on a layup track near the Bowery station of the J and Z trains on the Lower East Side were tagged Sunday night.
Trespassers, especially young ones, breaking into parked trains has become a persistent issue plaguing the subway system in recent years.
Two months ago, a thief stole the control stick from an R train parked under southern Brooklyn — the same section of track where a repeat train thief recklessly threw a train in reverse during a joyride months earlier.
A teenage crew gained notoriety in January 2025 for breaking into a pair of R trains and moving them at speeds up to 30 mph along a section of express track in Brooklyn.
